Kerrin Arfsten has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Anti-reflection UV-blocking multilayer coatings having a thin film layer having cerium oxide, silicon dioxide and transition metal oxides
    Publication number: 20050158591
    Abstract: An antireflective multilayer coating including a thin film optical coating as well as a method for producing such a coating are provided. The thin film optical coating includes a layer of sol-gel derived cerium oxide, silicon dioxide, and at least one oxide of a transition metal selected from Group IIIB through Group VIB of the Periodic Table which is capable of providing a refractive index of at least about 1.90. The thin film may optionally include colloidal gold particles. A method is provided for producing a thin film optical coating including a layer of sol-gel derived cerium oxide, silicon dioxide, and at least one oxide of a transition metal selected from Group IIIB through Group VIB of the Periodic Table by immersing a substrate in a solution comprising cerium nitrate hexahydrate, an alcohol and a chelating agent, withdrawing the substrate from the solution and heat treating the coated substrate to form the metal oxides.
    Type: Application
